P51 Enerpac Low-Pressure Hand Pump is a 3,000 psi single-speed pump with a 50 in³ oil supply. It provides more reservoir capacity than the compact P18 without the size of the 200 in³ P25 and P50 models.
Horizontal Low-Pressure Pumping
The P51 has a specific installation consideration: Enerpac designates it for horizontal operation only. That makes it a good fit for bench, fixture or machine setups where the pump can remain level rather than being carried and operated in changing orientations.
An external load-release valve controls the return of single-acting cylinders and tools, and the internal pressure-relief valve protects the pump from overload. Its single-speed design keeps the hydraulic response consistent from start to working pressure.
Choose P51 when a moderate 50 in³ oil capacity and 3,000 psi rating match the system. For vertical mounting flexibility or substantially more reservoir volume, compare the other low-pressure P-Series models.
